One of the biggest misconceptions on the internet is that the sites that we access for free every day are also free to set up and manage. The truth is that this site's administrators pay thousands of dollars every year. Many sites get their revenue from advertisements. Not here. Simnetwork depends mainly on user donations. This year's $6,000 goal is to pay for both the .com page with these forums and the downloads archive and the .net page

As of this writing, we currently have 16,757 members, if only 600 were to give only $10,00 we would meet our goal.

The Airco DH.4 was a British two-seat biplane day-bomber of the First World War. It was designed by Geoffrey de Havilland (hence "DH" for Airco, Production was by Airco, F.W. Berwick and Co, Glendower Aircraft Company, Palladium Autocars, Vulcan Motor and Engineering, and the Westland Aircraft Works in the UK. A total of 1,449 aircraft (from orders for 1,700 aircraft) were made in the UK for the RFC and RNAS.[5] SABCA of Belgium made a further 15 in 1926.

Arado Ar 234 was the world’s first operational jet-powered bomber, built by the German Arado company in the closing stages of World War II. Produced in very limited numbers, it was used almost entirely in the reconnaissance role, but in its few uses as a bomber it proved to be nearly impossible to intercept. It was the last Luftwaffe aircraft to fly over England during the war, in April 1945. The Ar 234C was equipped with four BMW 003A engines, mounted in a pair of twin-engine nacelles based on those from the eighth Ar 234 prototype. The primary reason for this switch was to free up Junkers Jumo 004s for use by the Me 262, but the change improved overall thrust, especially in takeoff and climb-to-altitude performance. An improved cockpit design, with a slightly bulged outline for the upper contour, also used a much-simplified window design for ease of production. Airspeed was found to be about 20% higher than the B series and the faster climb to altitude meant more efficient flight and increased range.

Icarusgold just published few screenshots about their model in a beta 01 version. Check out new icarusgold Arado's screenshots here:
